Update

The Zr. Ms. Pelikaan of the Royal Dutch Navy is a support vessel stationed in the Caribbean and is mainly used for humanitarian aid in the area. The vessel will reach its half of the intended lifespan, therefore a midlife update program is planned.

Inclination test

Due to the changes that will occur during the midlife upgrade it is important to determine the current status of the ship stability, center of gravity and lightship weight. Now the upgrade has started a lot of weight will be added and removed, these changes will obviously affect the values. We provided the inclination test to find the correct values of the lightship weight and center of gravity. Another inclination test will be carried out by us at the end of the midlife upgrade. The differences between the two inclination tests will result in a new stability, lightship weight and center of gravity.

Modifications

During the midlife upgrade the vessel will undergo different kinds of structural modifications and new operational equipment. And some minor changes in the interior so the crew has a separate living space on board and the vessel will be gender neutral. Some other examples of these adjustments were:

  • The engineering of a new foundation for a water transport pump
  • A new staircase between the deckhouse
  • Placement of a 500 liter buffer tank
  • Creating new spaces in the accommodation for the crew and visitors

Deck crane
One of the most challenging tasks, was the engineering of the new deck crane that had to be placed on board of the vessel. The new FRISCs that needed to be stored on board are bigger than the earlier models. Therefore a new crane is necessary with a larger capacity while having a bigger outreach. To guide the FRISCs safely onboard some structural changes were needed like replacing the life rafts. And adjustments to the hull, providing the railing with bumpers and place extra deck lashings for the sea fastening of the cargo. FEM analysis were made to check the forces that will occur in the pedestal, deckhouse and surrounding structure to guarantee the structural strength of the vessel. We provided the production, demolition and assembly drawings for all adjustments described above.
