RNLI
Green
Marine has had a long and successful relationship with the Royal National
Lifeboat Institution (RNLI). To date we have built over 100 Lifeboats
and also carry out refits on the Mersey class lifeboat.
It
was the awarding of a very new type of contract that started Green Marine
on the road to building for the RNLI. Back in the mid ‘80s we
were asked to look at an ambitious design for a landing craft capable
of 40 knots that had to be a good sea boat and carry 12 soldiers. With
the help of composite materials suppliers and engineering consultants,
SP Systems, Green Marine took on the work.

The
boat was a huge success with her owners and proved important in SP Systems
pitch to the RNLI for a new generation of lifeboats.
Lured
by the prospect of lighter, faster boats the RNLI were also impressed
by Green Marine’s practical experience with modern sandwich construction
for race boats. They awarded us a contract and in 1988 our first Fast
Carriage Boat (Mersey) was launched. That
marked the start of a production run of 26 more boats in just 4 years.
Next
came the contracts to build the new Severn and Trent
class lifeboats – of which over 80 have been completed to date.
The RNLI call these boats 'all-weather craft' and they’re not
kidding. They operate in the waters of some of Europe’s most inhospitable
coastline, leaving port when everyone else is looking for shelter.
Each
boat has over 100mm thick foam cored topsides, single laminate double
hull bottom, 4 water-tight bulkheads and prepreg epoxy glass/Kevlar
laminates – these boats are built to last and are likely to see
out their 25 year service life with ease. In service now for 12 years
they have proved to be extremely resilient and damage resistant so far.
In 1999 Green Marine was delighted to be appointed builder of the experimental
version of the new Fast Slipway Boat - now called the
Tamar class - the latest addition to the RNLI fleet.
The Tamar design is for a 25 knot, 28 tonne fibre reinforced
composite boat to replace the RNLI's Tyne class slipway
launched lifeboat.

Without doubt lifeboat crews are amongst our most demanding customers
– they operate in the most demanding of conditions and not surprisingly
expect the highest standards for their craft.
The
pre-production boat will go to DML in Plymouth for fitting-out and is
due to hit the water at the end of summer ‘04. Work will start
on the first of four production boats in early 2004 and these will be
completed during the course of 2004 and early 2005 with an expected
build time of 5 months each.

and superstructure has been laminated as a solid one piece glass mould

We
don’t just build new lifeboats – we also service and refit
many of the boats we built years before: the Mersey class boats have
a re-fit every 5 years and this involves the boat returning to one of
our Lymington factories where she is taken completely apart, all the
fittings come off and the engines are removed and sent off for a total
overhaul. A re-fit averages 12 weeks and during that time we make any
necessary repairs, service all of the equipment and carry out any modifications.
We then re-paint the entire boat, inside and out, and all of the fittings
prior to reassembly. Once this is complete the boat goes back into the
water and the engines and electronics are commissioned. She then undergoes
a day of close scrutiny by an RNLI inspector and is declared “passed
out and ready for operational use”. Only then does she return
to her station.

FINAL
SEVERN CLASS LIFEBOAT LEAVES GREEN MARINE
After a total of 46 boats built the final Severn Class Lifeboat left
Green Marine’s Waterloo Road factory on Monday 15th December 2003.
It was
back in 1992 that the RNLI awarded the contract for 46 Severn Class
lifeboats to Green Marine; over that 11 year period our workforce has
more than trebled. There are now some 60 people, 50% of our staff, working
directly on RNLI projects. At the peak of production 8 Severn Class
boats left our Lymington workshop in a single 12 month period.
On Thursday
11th December many of the people who have been involved with the Severn
Class builds from both the RNLI and Green Marine gathered under the
hull in the factory for a celebration drink and farewell to the project.

The final
hull travelled by road from Green Marine to Berthon in Lymington for
fitting out. Once finished extensive sea trials will be carried out
before she takes up her post as a Relief Lifeboat – available
to whichever station needs her.

RNLI FCB2
The new RNLI FCB2 (Fast Carriage Boat) Experimental boat is being built
at Green Marine – Lymington. The boat is based on a Camarc designed
hull and will have two CAT 3126B engines and Hamilton water jets. She
will ultimately replace the Mersey class boats around 2007/8.

We have now completed the hull and deck shells, and are now fitting
bulkheads, engine and longitudinal stiffeners. The plan is to have the
basic boat structure finished by the end of August. Green Marine have
had the opportunity to input our extensive knowledge and experience
of composite structures into this project at an early stage and have
provided all the 3D modelling, drawing work and composite engineering.
We have developed a very clean simple structure that has been efficient
to build and that will be economic to build in production.
