Superyachttender puts firesafety firstSPECIALISING IN the supply of

custom and semi-custom

tenders to superyachts, UK

company Superyacht Tenders

produces a range of vessels

that focus on fire protection,

functionality and performance.

SP, the marine business of

Gurit, provided the composite

materials to help create a new

Lloyds tested superyachttender compliant with the

requirements of the UK

Maritime and Coastguard

Agency (MCA).

Working in partnership with SP,

the team at Superyacht

Tenders manufactured the hull

using a combination of

engineering materials which

included SPs ST70FR and

Ampreg 21 epoxy wet

laminating system, polyvinyl

chloride (PVC) core, and glass

reinforcements.

ST70FR, a fire retardant hot melt

SPRINT, is ideally suited to the

manufacture of laminates

requiring fire protection. SPRINT

materials consist of a layer of fibre

reinforcement either side of a

precast, precatalysed resin film,

with a light tack film on one face.

ST70FR is reported to be capable

of producing high quality, low

void-content components from a

low cost vacuum bag/oven

curing process. It was selected as

being the most fire retardant of

SPs structural epoxy systems

with the most external fire

testing certification.

The SPRINT format has low

smoke toxicity, is self extin-guishing and halogen-free.

To achieve Lloyds and MCA

compliance the craft had to

successfully withstand a series of

demanding tests, including fire

testing, being swung against a

dock, drop tested from 3 m, and

swamp tested.

The handling and processing

qualities of ST70FR made it ideal

for the manufacture of the MCA

Compliant Superyacht tender,while using Ampreg 21 delivered

significant benefits in our

production with reduced build

times and good health & safety

characteristics, says Paul Jennings,

MD of Superyacht Tenders Ltd.

Cured in placepipe lining systemA CURED in place composite pipe

lining system (CIPP) has been

used for a major sewer repair

project in Reno, Nevada, USA.

The project was carried out by

pipelining specialist Pipenology

Inc and involved lining a total

7.7 km of 20-183 cm diameter

sewer pipes both in the busy

downtown and rural areas of

Reno. With the CIPP process the

repairs were carried out via

existing manhole access points.

This approach was not only fasterthan more traditional pipe lining

methods but also eliminated

disruptive and potentially

damaging excavation work.

CIPP technology repairs ageing or

damaged pipelines by

constructing a new liner inside

the existing host pipe. In the case

of the Reno project liner

construction began with a special

felt tube of predetermined

dimensions and length. The felt

was impregnated AOCs Vipel

corrosion-resistant resin and then

inserted into the pipe via existing

manholes in order to eliminate or

minimise the need for excavation.

Pressurised water was then intro-

duced into the resin-impregnated

tube to invert it and move it

along and against the sides of the

host pipe. When the entire length

of tube was turned inside out, the

water used during the insertion

was heated to cure the resin.
