Inclining Test for Research Vessel Saentis After Modification

The 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.

Why an inclining test was required

An inclining test (or inclination test) was required after the removal of the helicopter platform. This modification reduced the vessel’s wind profile and improved station-keeping performance and fuel efficiency, but it also changed the lightship weight by more than 2%. As a result, the vessel’s stability needed to be verified.

Preparation and execution of the inclining test

The project had to be executed within a short timeframe, which created several challenges during the preparation phase. In close cooperation with the crew, our team prepared the vessel to meet the required conditions for the test.

Saltwater conducted the inclining test in the Port of Den Helder. During the test, the team determined the vessel’s displacement using draught readings from the draft marks, tank soundings, and a survey of items not included in the lightship weight.

Certified test weights were then shifted across the deck to incline the vessel, while the resulting heel angles were carefully recorded.

Data processing and stability analysis

The class surveyor supervised all measurements, which were documented for further analysis. After completing the on-site work, the team processed the collected data at the office to determine the updated lightship weight and center of gravity.

Reliable inclining test results under tight deadlines

This project highlights Saltwater’s ability to execute inclining tests efficiently, even under tight project schedules. By combining close coordination on board with accurate measurements and in-house analysis, we deliver reliable stability data that enables clients to update their vessel’s stability documentation with confidence.
