Teignbridge is pleased to have provided the full propulsion systems for Colombo Dockyard’s two new pilot vessels built for the Sri Lanka Ports Authority. We provided 1050mm x 1080mm x 5 Blade CUPPED S-QUIN, 105% DAR propellers with 90mm shaftline, all with Lloyds class approval.
“The pilot boats were of a revised repeat design supplied by Macduff Ship Design of Scotland. The launches will serve to transport pilots from shore to ship and can accommodate a total number of eight people including four crew members and four pilots.
The design brief matched very closely to that of Macduff’s recently completed series of three 19-metre pilot boats built for Saudi Sea Ports. The boats needed to achieve 22 knots at trials and offer good sea keeping characteristics to allow for safe operation. According to Macduff, there were some challenges with the increased range requirement, so additional fuel was required along with changes to engine ratings, but with the addition of two new midships fuel tanks, all requirements were met.
The propulsion system was kept as similar to previous vessels as possible, although the change in engine rating led to some challenges. The propeller design was completed by Teignbridge, which led to the preferred gear ratio selection to ensure optimal performance at the vessels’ operational speeds.” – Baird
