Intermarine UK, who design and build pontoons for marinas worldwide, has just completed two new floating boathouses for the RNLI (Royal National Lifeboat Institution) at their lifeboat stations based at Brighton in Sussex and Burnham-on-Crouch in Essex.

Built to accommodate the Atlantic 85 B class of rigid inflatable lifeboats, the RNLI boathouses have been designed with new operating requirements firmly in mind.

Common to both boathouses, the first of their kind in the UK, the basic structure is a U-shaped floating steel pontoon mounted with a clad steel superstructure frame. Constructed with full cathodic protection and low maintenance requirements, they should give good service over a minimum operational life of 25 years.

Other features include a unique hydraulically-operated lifting platform, supplied by Armada Hydraulics which allows for rapid launching of the lifeboats via a cradle mechanism. On return, the lifeboat can be manoevered vertically, which allows for easy maintenance of the craft.

Assembley of the boathouses was performed close to their installed locations because their size precluded transportation by road. At Burnham-on-Crouch, the yacht harbour slipway cradle came into play, whilst the larger of the two boathouses at Brighton was assembled in the Shoreham Port dry dock, and then towed and moored alongside the awaiting pontoon.

Robert Jeans, RNLI shoreworks engineer, has been with the project from inception: - "I am very pleased with the boathouses. All in all two very good projects, thank you."

The boathouse project team comprised civil engineer Peter Cross as overall project manager, naval architect Ian Darley, Four-Tees Engineers for fabrication of the steel pontoon walls and enclosure superstructure, TA Colbourne for superstructure cladding, Envirodoor for the lifeboat doors, and Dove doors for the lifeboat personnel doors. The electrical installations were entrusted to the RNLI-nominated contractor E J Thurston of Clacton-on-Sea.

From the receipt of contract in September 2010, the RNLI project has proceeded according to budget and plan. Tony Mayhew, RNLI's consultant engineer, was extremely pleased with the outcome: - "Intermarine have successfully delivered two bespoke floating boathouses for the new generation Atlantic 85 lifeboats. They have been responsive and a pleasure to work with throughout both contracts, both of which were completed on budget."

Given the charitable status of the RNLI, the project also represented good value for money with significant savings made against the initial tender figure.

Scott Gaherty, Intermarine Managing Director - "The RNLI project represents an exciting development in our range of bespoke solutions we can now offer the marine industry. We look forward to working with them again in the future."

Intermarine's previous work with the RNLI includes the training boat marina at the RNLI College at Poole in Dorset completed in 2004.
