Based on the drawings, pictures and electrical schematics obtained from the shipbuilder and ship owner, we can conclude that the bridge is fully in compliance with the requirements of the DNV rules section 7 Chapter 9 – 1 & 2: General requirements & Physical conditions.

The bridge arrangement of M/S MERSol meets the standard. The consoles and equipment are arranged in such a way that the OOW can comfortably and effectively perform their duties. The different workstations are clearly distinguishable, facing the right direction, and located in such a way that the navigation workstation can be monitored remotely. The entrance points to the bridge, distance between bridge wings, distance between consoles, and ceiling height are all in compliance with the regulations.

All items located on the bridge are without unnecessary sharp edges, non-reflective, and equipped with handrails where possible. Adequate seating is available at the various workstations, equipped with means for securing them during adverse weather conditions. The bridge has an adjustable climate control system, and the noise levels are within the 65dB limit. According to a noise measurement report by Bureau Veritas, the bridge has a maximum noise level of 60.7 dB, during full navigational speed with normal weather conditions. Electromagnetic compatibility (EMC) tests for the bridge have been carried out by the shipyard, with satisfactory results.

The requirements stated regarding the lightning on the bridge are met on M/S MERSol. as all workstations on the bridge are equipped with sufficient overhead lightning and illuminated buttons and screens, which are fully dimmable. Navigation lights, and floodlights situated on the bridge deck and monkey island are fully controllable from the bridge, the navigation lights are connected to the bridge alarm system.

The bridge is provided with two separate circuits for lightning, including emergency lightning. In the figure below the emergency lightning arrangements for the bridge including the type of lightning fitted are shown.The emergency lightning on the bridge is red instead of white.

The requirements stated regarding the windows on the bridge are met on M/S MERSol. All windows are made from thermally toughened safety glass, and they are well within the acceptable limits regarding heights of lower edge, upper edge, and incline. The windows are wide, there is no division directly in the ship’s centreline, and the total number of divisions is kept to a minimum. A DECCA heavy duty wiper and washing system is installed which can keep most windows clear of water during adverse weather conditions. The system is also capable of washing the windows using a combination hot/cold potable water, supplied to the windows through a system pressurised by air. In figure 7 the dimensions of windows, their locations, and specifications are shown.

The requirements stated regarding the fields of vision, are for the most part met by M/S MERSol. With the exception of the requirement that states that a straight line of sight between bridge wings is to be realised. The respective distances, angles, layouts, and fields of vision are illustrated in figures.
