Inclination test
The Geoquip Saentis is one of Geoquip Marine’s geotechnical research vessels. Built in 2005, she was repurposed and outfitted for geotechnical research in 2019. Since then, several upgrades have been carried out to maintain her suitability for this demanding market.
The purpose of the recent inclination test was to verify the vessel’s stability following the removal of the helicopter platform, which resulted in a lightship weight change of over 2%. The helicopter platform was removed to reduce the vessel’s wind profile, which results in improved station keeping and lower fuel consumption.
Short timeframe
The project was executed within a short timeframe, presenting challenges during the preparation phase. However, in close cooperation with the vessel’s crew, the vessel was successfully prepared to meet the necessary conditions for the test. The inclination test took place in the Port of Den Helder.
To measure is to master
The vessel’s weight was determined using draft readings from the draft marks, tank fillings measured via tank soundings, and a survey of items not included in the lightship weight. The vertical center of gravity was established by inclining the vessel using certified test weights. After each weight shift, the inclination angles were recorded. All measurements were carefully documented under the supervision of the class surveyor and brought back to the office for further analysis.
At the office, the inclination test data was analyzed to determine the updated lightship weight and the corresponding center of gravity. These results were then provided to the client, who will have the vessel’s stability calculations updated by a third party.
