A crane (1) for a vessel comprises a main boom (2) and an auxiliary boom (3) having a smaller length than the main boom (2) and being tiltable with respect to the main boom (2) about a tilting axis, a hoisting cable (4) which suspends from a cable guide (6) at the auxiliary boom (3) and a drive system (9, 11) for tilting the auxiliary boom (3) with respect to the main boom (2) in order to compensate for motion of a vessel. The tilting axis forms a first tilting axis (7) and the auxiliary boom (3) is also tiltable with respect to the main boom (2) about a second tilting axis (8) extending transversely with respect to the first tilting axis (7). The cable guide (6) is located at a distance from the first and second tilting axes (7, 8).
A system for cleaning and sterilizing a water flow comprises a main treatment line with a pump to pump water from a water storage, a main filter, a sterilizing station and a system outlet. The main filter is provided with a first filter element and a backflush member to rinse the first filter element with backflush water. The secondary treatment line connects to an outlet of the backflush member, and has a backflush filter to remove silt from the backflush water. The main filter is designed such that the pressure difference over the first filter element is at least 0.1 bar (10 kPa) and the backflush filter is designed such that the pressure difference over the backflush filter element is less than 0.05 bar (5 kPa).

The deformation portion comprises a plurality of resilient connection elements (15) which are fixed to the front wall (7) in respective front wall junctions (16) spaced from each other in a direction parallel to the front wall (7) and the upper side (11), on the one hand, and to the rear wall (8) in respective rear wall junctions (17) spaced from each other in a direction parallel to the rear wall (7) and the upper side (11), on the other hand. Each of the connection elements (15) has a length between the front wall (7) and the rear wall (8) which exceeds the shortest distance between the front wall (7) and the rear wall (8) at its corresponding front wall junction (16) or rear wall junction (17), as measured in a direction from the shock-absorber side (9) to the fastening side (10). The number of front wall junctions (16) as well as the number of rear wall junctions (17) is less than ten per meter, preferably less than seven per meter. Two neighbouring connection elements (15) are attached to each other at an intermediate junction (18) located between the front wall (7) and the rear wall (8).

The invention relates to a system for cleaning and sterilizing a water flow. The system comprises a main treatment line (1) with a pump (56) to pump water from a water storage, a main filter (8), a sterilizing station (20) and a system outlet (30). The main filter is provided with a first filter element and a backflush member to rinse the first filter element with backflush water. The secondary treatment line connects to an outlet (17) of the backflush member, and has a backflush filter to remove silt from the backflush water. The main filter (8) is designed such that the pressure difference over the first filter element is at least 0.1 bar (10 kPa) and the backflush filter is designed such that the pressure difference over the backflush filter element is less than 0.05 bar (5 kPa).

A laminated element (1) comprises a core (2) and at least a sheet (3). The sheet (3) comprises a fixed portion (3a) which is attached to the core (2) and a loose end portion (3b) which is separate from the core (2). In assembled condition of an assembly of the laminated element and another element (1') the laminated element (1) is fixed to the other element (1') through a joint (5) between the loose end portion (3b) of the sheet (3) and the other element (1').
The invention concerns a ship (1) comprising a hull (8) and a length that is less than 3.0 times and preferably less than 2.5 times a beam of the hull, located forward of the amidships two propulsion and steering units (6) with a propulsion drive for rotating propellers around a propeller axis (5) and a steering drive for positioning the propeller axis at a steering angle relative to a centreline (20) of the hull, and rearward of the amidships stationary course stabilising skegs (9) located symmetrically on both sides of a centreline (20) of the hull. The distance between the fronts of the stabilising skegs is between 30% and 70% of the beam and preferably between 30% and 70% of the beam.
