[Music]

aboard welcome to Maritime matters the

Marine link podcast I'm your host Greg

troutwine editor and publisher of

Maritime reporter and Engineering news

for more than 30 years Our Guest today

is Bob Lennon the industry manager senta

a Regal Rex Nord brand that has a long

and storied business in Marine couplings

to discuss the Advent of hybrid

propulsion Solutions across Maritime

with insights on their engineering

impact for the entire drivetrain Bob you

know as I mentioned I've been in this

business for about three decades and I

know the senta name very well um but as

we've seen there's been a massive am of

consolidations across all Maritime

companies I guess to start us off the

best way um that I believe that we could

start off if you would provide some

context here specifically a look at the

long history of the senta brand and what

I like to call my Christmas Carol

approach senta's past senta present and

if you can delve into it senta future so

the the company was started in 1970

German engineer gentleman named Gart

kirai and Gart was working on a project

project with one of the diesel engine

manufacturers to make a centrifugal

clutch that could be put on the flywheel

of the diesel engine run the engine at

idle speed disconnect the

load with the coupling elements of the

day Gart couldn't get the clutch to

operate so he came up with a patent for

our basic rubber element cenlex series a

first company patent um pre-compressed

rubber in compression

he was able to put that element then

into the design of a

clutch and the first company product

sent to start V was literally a cical

clutch for diesel engine driven

equipment name of the company senta

derived from that first product

cental and 1970

launched um Gart found a really good

niche in engine driven equipment so the

early years of a company was more

industrial

focused um came up with a few more

patents and got

into you know diesel engine driven pumps

and then diesel engine driven

Hydraulics came on the sea construction

equipment so we came up with a couple of

patents there and we did a number of

years Global Leadership in things like

hydraulic

excavators um road paving equipment the

construction Markets started to use

diesel engine and hydraulics for a lot

of their powert train and sent to found

a global leadership role there pretty

early years going by crept into some

stuff in terms of power

generation you know pretty similar

application an engine driving a two

bearing generator

now uh commercial power primary standby

power we also crept into wind power

pretty early on uh had a few years where

we had a really good market share and

the the landbased wind turbines maybe up

to about two megawatt

um and then a few years

in bigger bigger engine drives and

Marine propulsion became a natural for

the for the next Market

Evolution um few more patents over the

years and built out a fantastic

portfolio of both Marine propulsion and

power takeoff

cou coming into probably the early

1990s Gart then innovated carbon fiber

and he patented a method to bond carbon

fiber to

steel and we hit a really good one with

high-speed fairies you know aluminum

catamaran vessels and Ultra lightweight

carbon fiber

shaft so the business really blossomed

um Marine propulsion became a big part

of it um and then you crept into the

world of you know EPA and the Europeans

with lower emission

uh tier two tier three tier four engines

becoming more torsionally active and our

business just through the 2000s really

took

off um built up to the point where we

were about um just under 500 Global

employees and the kirai family the two

boys running the

business um I think there were nine

daughter

companies we got into our own rubber

production with a joint

venture couple of liy

agreements and then

2018 the business was sold to

rexnord rexnord a well-known brand in

mechanical Power

transmission they had a little space in

Marine they had the Legacy folk the folk

Marine Transmissions were part of our

portfolio and you know bearings and

couplings and gearboxes for industrial

drives so 2018 acquisition rexnord

come up to

2021 and rexnord merged with a company

called Regal bullet another Wisconsin

company and Regal boo brought more

portfolio more Brands not only

mechanical Power transmission gearboxes

bearings Etc but electric

motors um shortly after that last year

we then did an acquisition of another

company group called Ultra

so present state in the last few years a

lot of merger a lot of

acquisition but the Regal rexar brand

today is over 70 individual Market

leading

Brands mechanical and electrical power

transmission motion control automation

conveying um really cover a great gamut

of

markets and you know the senta being a

key in in Marine propulsion in power

generation

and even still off Highway construction

equipment and

agriculture couple other brands that

came into the mix with the Acquisitions

in the mergers we've got the guardian

Product Company out of Michigan City

Indiana good position in off Highway

construction equipment Diesel

hydrostatics and then another German

coupling brand stromag came in with the

ultra acquisition and Strow mag's got

some fantastic technology and clutches

and

Bricks plays into hybrid drives for us

for future

technology um group out of Spain that

came along with Regal called y yar's got

a fantastic Global presence in drive

shafts and couplings Thruster drives

water jets so we've really built a

fantastic group here um where New York

Stock Exchange were 7 point something

billion dollars in annual

revenue uh 35,000 plus employees um um

so it's been a ton of fun you you know

you joked about three decades it dawned

on me recently I think I've now clipped

through

four um went by in a blink of an eye but

it's been a lot of fun to see the

transition of the company you know the

future um who knows but Regal Rex st's

got a real Vision on not only you know

product innovation's important

sustainability is a big part of the

mission and and that's the way the

markets want to go you know everybody

wants to be greener everybody wants to

be more environmentally responsible and

I think we've got a great u a great

platform here to build on that for many

years to

come w b you're you're you're I I love

these conversations because you're a

font of information not just about your

company about but about the industry as

well and it is funny actually those

those 3040 years tend to go very quick

because I I very well remember the first

time that I I joined this company my

first event was the smm in Hamburg

Germany and

1992 and I went over there and there was

there was a group of uh uh British

journalists that were you know dominant

in the field and you know I remember

walking into the press conferences and

I'm like look at all these old guys and

then uh probably fast track to that

about 2018 before the pandemic shot us

down I was over an event and I walked

into the same type of press conference

and I looked around I'm like uh oh I'm

the old

guy everybody there looked like they

could be everybody look like they could

be my kid so you know Bob that's

interesting can you uh you know I I

appreciate that overview um when you can

you give us a little I I guess of your

background you've been in this business

almost 40 years like you said or a

little over 40 years um how how long

have you been with the company can you

just give me kind of a a walk through of

your experience in this

business yeah I was laughing as you were

talking because I I followed my father

into this I'm second generation oh wow

never had a clue I'd do this my entire

career but I'm glad I did um my dad when

I was a young guy had been in mechanical

Power transmission retired marine and he

took up as sales manager for a company

in Aberdine South Dakota company called

Hub City interestingly enough a current

Regal rexnord brand um but then Dad

transitioned down to a company called

Lovejoy here in Chicago vice president

sales and at that time Lovejoy and senta

were forming their global licy

agement um my dad and oldest brother a

few years later formed a rep

agency 1975 or six mechanical Power

transmission products and they had the

Lovejoy brand as their lead line so

they're covering the north central

United States as

reps I'm going to college in the early

80s decided to chase a mechanical

engineering degree no clue what I wanted

to do and my dad got me a summer work at

Lovejoy in Downers Grove as a

machinist so I'm spending Summers and

breaks running Machine Tools punching

Boors and keyways drilling out set scers

all the time thinking yeah maybe I'll

stay in college I'll finish my degree I

think that was his

motive um but I graduated in 85 I think

and just joined the rep firm right out

of college so my dad's taken me to trade

shows you know Chicago McCormack place

the big mechanical Power transmission

show

and just like you said I'm looking at

all these old guys but all this really

cool equipment hey this isn't bad

started making sales calls with Dad you

know caterpillar was a big account of

ours early on um and just never looked

back I did the rep thing for about 23

years ton of fun met a lot of great

people and then in 2005 some friends of

mine had started Senate Corporation the

US division love joy and sent aparted

ways um so I had the opportunity to join

C Corp as VP of sales about

2005 um and just you know helped and

watched that company grow until we were

acquired by by rexnord in

2018 currently serve a role as you know

industry manager is kind of the term but

I'm I'm the subject matter expert I do

business development work I'm here in

our Milwaukee headquarters for a few

days this week do training for some

young sales engineers and like you said

all of a sudden it's 40 Years Gone so

it's been a lot of fun been a great trip

Regal Rex nord's 30,000 Global

Associates work to create a better

tomorrow by providing Sustainable

Solutions that power transmit and

control motion with a comprehensive

portfolio of Highly engineered power

transmission components and subsystems

Regal Rex Nord Engineers design

efficient and long- Lasting Solutions

including Factory automation food and

beverage Aerospace data centers

warehouses metals and Mining and of

course Marine propulsion Regal Rex Nord

is headquartered in Milwaukee Wisconsin

and has manufacturing Sales and Service

facilities worldwide for more

information visit Regal Rex nord.com so

Bob again I appreciate that personal

background I appreciate the corporate

background background let's kind of look

at senta today and into the future I

guess uh because you know everywhere we

look uh and everything we're talking

about now um you know we're talking

about energy transition you're talking

about hybrid propulsion

Solutions um and

undoubtedly this is going to last for a

long time because obviously you know oil

and gas you know is here to stay for a

while there is a transition going on

right now and but there is there is an

increasing push towards the hybrid

Solutions um there is of course no

single definition of hybrid but can you

discuss how the Advent of various hybrid

propulsion Solutions are impacting the

drivetrain as a whole and you know what

is your team what can can you just kind

of relay some of the conversations that

your team are having with clients today

in regards to hybrid systems and its

impact on the

drivetrain yeah it's a great topic and

it's funny again to think back over the

years because you and I might have first

cross paths in the early conferences

when they first started talking about

EPA tier two tier three and oh my God

someday we got to hit tier four and the

engine guys in the room all grounded and

said how are we going to get there and

the industry did it um I was sitting at

a conference recently and now you're

talking about you know hybrid and

alternative fuels and hydrogen fuel

cells and Battery you know the Ewolf is

running battery boats are running and

one guy in the room raises his hand and

says what the heck's wrong with my tier

four final engine you guys told me to

get a tier four final engine and the

room kind of

chuckled um I don't think anybody knows

what that future looks like but you know

hybrid is going to be a transition phase

technology my opinion um alternative

fuel is probably something that'll stick

around but I don't think they know what

that's going to look like

yet and even the hybrid isn't defined

because everybody's trying to do it a

little bit

differently um Sena Corp was actually

involved

I forgot the year 20067 maybe um but you

might remember Foss building the first

hybrid tug boats on California there

absolutely Dy and then they did a

retrofit of a second boat maybe the

Campbell I can't recall um but senta was

a big part of that project with the

propulsion integration team you know

they took a diesel engine they put a

clutch on the flywheel with a scent of

coupling we made a little sh shaft and

then they dropped a motor generator in

line in that shaft loaded the boat with

batteries you know variable frequency

drives power conversion lots of wires

and they tried it and they had they had

some success with it um they learned a

lot and you know how many years ago

again was that we were trying to get to

hybrid um you go to the shows today and

hybrid has different definitions because

some people with the gearbox they'll put

a PTO PTI motor generator on the gearbox

drive you can use that to pull power out

charge batteries or you can use it as a

propulsion adjunct with or without your

main propulsion adjunct um some people

are putting it on the back you know I've

seen Z drivers with a PTO PTI motor um

again we did one of the first boats uh I

think it was built for or by Bay Delta

at Nicholls maybe forgot the name of the

vessel but they they put a couple

hundred kilow wat motor on the Z drive

for PTO PT hybrid um so what's it going

to look like in the future I'm not

sure I don't think there's an argument

that we don't know how to create

anything as power dense yet as you know

internal combustion and diesel

fuel but they're trying that's where

alternative fuel technology is starting

to

Blossom um you know a few years ago

again at the conferences everybody was

talking LG we're going to be LG in five

years and now they've kind of moved on

there's LG out there for sure no doubt

great fuel but you know now I go to

conferences and I hear them talking

about

ammonia and yeah it's all over the

country you know your farmer next door

has an anhydrous ammonia tank so fuel

bunkering handling Transportation we've

got ammonia figured

out but what does that do in a cylinder

or the engine you know what's its burn

capacity what it what's its ability to

create

torque um so the future I don't think

they know what it's going to look like

but I think we'll transition through

hybrid and make our way to alternative

fuels and then someday we'll all end up

driving around little cars like the Jets

and what BET's going to be fueled by who

knows but hybrid's here it's real and um

you know a lot of us are figuring out

how to deal with it right now are are

there any particular uh problems that

you've been seeing in terms of alignment

um whether whether that's on install

whether that's on you know after years

of running um are there any I guess I

don't want to say tips or tricks but are

there any issues that you've seen um

that senta and Regal Rex Nord are able

to help

solve in terms of just system alignment

you know mechanically making sure

everything's lined

up it's a longstanding discussion we

have it daily with

customers um you know the coupling guys

ourselves included like to say that we

make products that are highly

flexible but in terms of installation Mr

Shipyard you know the millright

folks and our manuals I want you to

align as close to zero as you can get

that equipment and today the guys are

getting good you know they're using

lasers they're paying attention to it um

there are some fantastic thirdparty

groups in the industry that specialize

in alignment specialize in

vibration um so yeah that's a that's a

regular topic of discussion for us I

will always be a guy to preach near zero

near perfect alignment at installation

and let those components give

compensation for operation for shock

load for whatever you know whatever

things The Vessel May encounter to wrap

up can you give a concise overview uh I

I put 60 seconds or less but I'll give

you 90 seconds uh you know a bullet list

of advice that you're delivering to your

clients today the dos and don'ts of what

you consider what of what to consider

when building out a hybrid propology

solution to help ensure that it has a

good long efficient

life yeah maybe I'll take 95 seconds and

and two two big points but let's go back

to

hybrid you know as a torsal coupling

supplier myself or anybody what we're

going to ask you for is as early in that

project as you

can get the experts engaged you know

work with the best work with people that

know what they're doing and have success

under their belt um because there's a

lot of unknowns and from our

perspective I need to know all these

components that you're putting onto the

drivetrain I need their mask their

inertia their stiffness but most

important I need the operating

conditions

you know the power and the speed when

are you going to be taking it from here

engine when are you going to be taking

it here from motor and what are the

combinations of those scenarios because

all of those operating modes have a

really important influence in that

tourism vibration calculation and the

results of the

calculation the second side of that when

you got that boat about done and you're

doing C trial get an expert on board get

somebody on the boat that can instrument

the power train and measure not only the

torsional response but the torque you

know are you creating the torque you

thought you were and the lateral motions

the the displacements XYZ stuff um

measure that data compare back to your

calculations and validate if you were on

target or not you'll learn a lot because

there's a lot of unknowns going into

these drives today the second side of it

my preach is is back to that maintenance

side and align

um plan your maintenance Cycles

carefully everybody knows when they're

going into dock for an engine overhaul

repow but it's inevitable that somebody

then starts taking off guards around

rotating equipment and they go oh gee I

need a coupling so you know again myself

the competitors I don't care who we get

the phone call of I need it now and oh

by the way the vessel's ABS so I need

that surveyed you know I need a

certificate for

it plan your dry docking and your

maintenance Cycles carefully look at the

rotating

equipment capture your drawings class

certificates if appropriate and have all

this stuff ready to go we've got a great

distribution Network around the country

work with a local distributor have them

carry critical spares so if something

breaks you've got it local but work with

those distribution Partners around your

maintenance Cycles plan it accordingly

and and let us keep out of being in

panic situations with delivery frankly

of a lot of product that comes out of

Europe so that's my preach thank you

good preach you might have gone over 95

seconds but that's quite okay

communicate well and plan I think that's

I think that's good for for a lot of

things in life so Bob it's truly a

pleasure I you know I I again like you

said we' we I know we probably knocked

around early in in in the early days but

you know we' we've seen each other quite

a few times and I truly appreciate your

insights I look forward to working with

you and your team in the future as
