The most unique feature of submarine design stability is that, unlike ships, submarine stability is studied under two conditions: Surfaced Stability & Submerge Stability.

💡 Safety in Navigation: Vertical divergence in maritime lanterns 🚢.   In the complex maritime environment, safety depends on small but crucial technical details. In accordance with the guidelines of the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA), maritime lanterns consider not only colour, light range and rhythms, but also degrees of vertical divergence to avoid false signals. Let's talk about IALA guideline G1065, this guideline addresses the vertical divergence of the light beam on Aids to Navigation (AtoN), specifically regarding their orientation and range. This guideline emphasizes the importance of ensuring that the light emitted by AtoN is clearly visible and understandable for seafarers. Vertical divergence of the light beam refers to the angular extent of the luminous pattern in the vertical direction, and Guideline G1065 provides specific guidelines to optimize this feature. The guideline establishes detailed criteria for vertical divergence based on various factors such as the type of AtoN and its purpose. These criteria are designed to ensure that light is projected efficiently and effectively, providing necessary information to seafarers, and minimizing the possibility of confusion or misunderstandings. Furthermore, Guideline G1065 underscores the importance of competent authorities implementing control and maintenance measures to ensure ongoing compliance with these specifications and the integrity of the maritime signaling system. I hope this short summary will be interesting for all of you! 💪 #G1065 #Divergence #Aton #IALA

Just in! Yesterday we received the bow thruster tunnels for a BU100 double transverse thruster system. In the picture you can see them in their raw state.   Each unit will be delivering 500kW and is specifically engineered for modern mega yachts with the highest demands when it comes to noise and vibrations.   This system combines the following key features: -     Jastram’s ANR air injection to suppress tunnel cavitation -     Custom-designed and optimised tunnel inlets -     Intelligent dual control system -     Special skew-design propellers with preferred working direction

Coandă effect: The thruster challenge The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect, which describes the tendency of a fluid jet to stay attached to a convex surface. For instance, under certain conditions (e.g., when a ship moves through water), the Coandă effect changes the direction of a propeller jet, causing it to follow the shape of the ship’s hull. The side force from a tunnel thruster at the bow of a ship decreases rapidly with forward speed, but a key challenge is that the bow thruster is used for low-speed maneuvering. The side thrust may completely disappear at speeds above about 3 knots.

What Is The Pivot Point Of A Vessel? Maneuvering is the ability of a vessel to turn towards the port or starboard side using the steerage force stemming from the turning of the rudder aft based on diverse requirements. These requirements can be anything like maintaining or changing its desired course of travel, trying to steer clear of an obstruction underway, or approaching a #port or #dock. Maneuvering is a broad topic in naval #architecture or vessel sciences and has been a matter of serious discussion and research for years. Many of us are also aware of the maneuvering trials that take place to assess the turning abilities of a vessel. Before discussing the pivot point of a #vessel, it is crucial to revisit a ship’s ‘turning circle’ maneuver briefly. A turning circle maneuver is when the vessel constantly turns towards a particular direction such that it completes or tends to complete a full circle after some time and returns to its origin or starting point. This is a common aspect of transportation, starting from vehicles like cars or two-wheelers. Similarly, a turning circle is achieved for vessels by simply applying the constant rudder moment towards a particular side. What is a #pivotpoint of a vessel? During stages of turning, the vessel’s turning moment acts about a definitive point of action, which lies on its centre-line, somewhat towards the fore-end or aft end. This kinematic point of action is known as the pivot point of a vessel. 

In the near future, the vessels must come to the so-called “zero discharge”, and for this, to obtain hybrid or electric power plants that provide reduced fuel consumption, or use its environmentally friendly types: LNG, hydrogen or wind. In addition, reducing harmful emissions into the atmosphere contributes to the development of the use of electric propulsion systems (EPS).

VESSEL REVIEW: French cargo transport company Grain de Sail has expanded its fleet with the recent acquisition of a new vessel delivered by local shipyard Piriou. 'Grain de Sail II' was built at Piriou’s Vietnam facilities to a design by French naval architecture firm L20Naval. It is notable for its large sails, which make it the second vessel in the Grain de Sail fleet to have such features. The rigging is developed using proven technologies and industry practices in construction and maintenance, resulting in a sail-to-displacement ratio of 2.5 square metres (27 square feet) of sail per tonne. This ratio means the ship can reach speeds of up to 12 knots while making it possible to reduce carbon emissions by more than 90 per cent compared to a conventional ship on an equivalent journey. The main goal of navigating without engine assistance is to reduce environmental impact as well as engine noise, which would otherwise have a direct impact on surrounding marine life. A series of trials undertaken in different weather conditions and with different sail plan configurations confirmed that the ship’s hull, coupled with its schooner rigging, is more efficient than expected in speed with optimum balance under sail. The vessel itself is also structurally designed to withstand cyclones, ensuring safe use in the Atlantic in all seasons. Full article link in comments.
