Pinfabb gives Fred.Olsen’s ‘Bolette’ a smoother ride

Genoa-based stabiliser repair company Pinfabb SRL, has retrofitted the stabiliser control systems on Fred.Olsen’s cruise ship ‘Bolette’.

Making use of Pinfabb’s POSEIDON system, the company said that the control system was renewed in the most optimised way to ensure the stabilisers’ longevity,  operate with minimal disruption or downtime, simplify the operations for the crew and reduce maintenance costs.

Overall, the stabiliser control system was upgraded and digitalised to take advantage of the benefits of remote monitoring, predictive maintenance and allowing energy/CO2 emissions reduction.

While the vessel was cruising in Europe, Pinfabb performed a full upgrade of the old stabilising control unit. On board the cruise ship, two Pinfabb service engineers undertook the retrofit with the help of  Fred.Olsen’s crew.

A new touchscreen panel was installed to replace the old bridge interface, to provide full   information to the operator regarding the real-time ship motion on the ship’s roll and pitch axis.

Pinfabb’s POSEIDON system provides analytical data about stabilisation and suggests the optimal use of fins. Weather data is also included to enable the operator to deploy the stabilisers as needed, depending on the sea conditions.

A new 10 inch touch panel was installed, as well on the engine control room (ECR) console.  All of the stabilisers’ data is displayed on the ECR console, including the status of the machinery and any future maintenance tasks, which need to be executed.

The plant’s operational information and automatic maintenance advice are at the operator’s fingertips to ensure the longevity of the whole – electronic, hydraulic and mechanical – system, thus avoiding any disruption.

A new and compact digital automation unit was installed near the existing hydraulic power unit (HPU). This unit monitors the status of the stabilisers and manoeuvres the fin locally being controlled by just two buttons.

As with all other POSEIDON systems installed, the stabilisers drag can be optimised, thus reducing the consumption as a result of the underwater friction. This is made possible by using the system under ECO mode.

The data collected remotely reported some interesting information, which demonstrated Fred.Olsen’s aim to pursue every small detail to reduce CO2 emissions and therefore optimise the function of all of the on board equipment.

The energy absorbed by the stabilisers can be cut by an average of 50% in respect of the absorption rate of a non-ECO system under the same conditions, the company claimed.

Depending on the on board comfort needed and the dynamic situation, POSEIDON automatically selects different stabilisation modes to give the most efficient angle of attack, always taking into account the best mechanical system compensation.

Pinfabb said that the mechanical plant compensation is an added value, as it demonstrates a practical example of how an ECO approach can lessen the mechanical stress and also reduces the leakage from the tilting piston after POSEIDON’s installation and especially after the integration of the ECO modality.

Analysis executed so far on the system data reported that no significant comfort deterioration had been recorded while sailing in ECO mode.

Matteo (Matt) Fabbricotti, Pinfabb CEO (pictured), said: “We have been proud and pleased to have Fred.Olsen joining the list of companies where POSEIDON is installed with the aim to digital transform their stabiliser systems.

“Working with Fred.Olsen has been a real pleasure, as the co-operation between the two companies has been very friendly and professional at all levels, from office to ship personnel. All the process as well from procurement to installation has been smooth,”  he added.
