“Shuttle tankers differ from “standard” crude oil tankers. To increase the regularity during loading operations and for the purpose of collision avoidance, they are equipped with dynamic positioning (DP) systems, which typically includes azimuth and tunnel thrusters both forward and aft. North Sea shuttles typically have a twin-screw propulsion system for redundancy and dynamic positioning purposes. In order to improve the position-keeping and manoeuvring capability in ballast condition, it is not uncommon that shuttle tankers have an increased ballast tank volume compared to standard crude oil tankers. Vessels designed for operation in rough sea areas such as the North Sea feature a hull design with increased fatigue life. As shuttle tankers load offshore, they all have a bow loading arrangement. Some existing shuttle tankers were built with submerged turret loading (STL) systems required for serving specific North Sea oil fields.” https://lnkd.in/ecEmRmje

👌 Marine Facts , Calculating Force due to Wind Most often ignored factor in shiphandling is effect of Wind, Ignoring which can lead to a serious incidents. Now we will try to quantify the effect of wind i.e. the force in tons, So that we can have a fair idea and its effect in practical ship handling. Understanding and able to calculate wind force is very critical to execute maneuvers in strong winds and avoid sudden accidents. As you can see from below table:- In case of VLCC in ballast, the force due to beam wind is 50 tons at 25 knots, i.e. it will take max power of 1 tug to just counter the effect of wind! So how many tugs do you think should be used? Hence vessel in ballast and vessels with large freeboard (Windage are 3000 Sq mtr or above) must properly plan their tug requirements if they intend to carry out pilotage in strong winds. If sufficient tugs are not available, movement must be delayed until wind has reduced. In no case movement should be attempted without thorough planning and tug requirements as at slower speeds and while maneuverings in Harbour or close to berths wind force will take over the vessel and in no time things can go out of control. 👉 In case of wind gusts upto 35 kts this force will become 72 tons hence vessel may easily go out of control if sufficient powered tugs are not available. 👉👉So with above understanding I hope you will be able to make better decisions if you should carry out or postpone pilotage in strong winds.

How do we keep an oil rig steady in a stormy sea?🌊 This question might seem like a puzzle, but we have the solution. Watch our time-lapse where a team on an anchor handling tug tackles incredibly heavy-duty work. They maneuver anchors weighing 12 tons each to securely anchor the platform. These anchors aren't just heavy; they're designed to withstand forces up to 500-600 tons, preventing the platform from moving even in the strongest storms. #offshore #shipping #maritime #oilandgas #marine #northsea #ahts #northsea

There are several types of tugboats, each designed for specific purposes and operations: 1. Conventional Tugboats: Traditional tugboats with a propulsion system and winches for towing. 2. Azimuth Stern Drive (ASD) Tugboats: High-performance tugboats with 360-degree rotating propulsion units. 3. Tractor Tugboats: Tugboats with propulsion units that can rotate 360 degrees, providing high maneuverability. 4. Voith Schneider Propeller (VSP) Tugboats: Tugboats with a propulsion system that uses a cycloidal propeller for high maneuverability. 5. Rotortug Tugboats: Tugboats with a propulsion system that uses three azimuth thrusters for high maneuverability. 6. Offshore Tugboats: Large, powerful tugboats designed for offshore operations. 7. Harbor Tugboats: Smaller tugboats designed for harbor and coastal operations. 8. Icebreaking Tugboats: Specialized tugboats designed to operate in icy waters. 9. Ocean-Going Tugboats: Tugboats designed for long-distance ocean towing. 10. Emergency Response Tugboats: Tugboats designed for emergency response and rescue operations. Each type of tugboat is designed to meet specific operational requirements and environmental conditions.

🚢 What is Bollard Pull and Why Is It Important for Marine Operations? 🚢 In the maritime world, bollard pull is a vital measure of a tugboat’s towing power. It represents the force exerted by a vessel when pulling a fixed object, typically measured in tons under controlled conditions. This measurement is essential for ensuring that a vessel has the necessary power to handle tasks such as towing large ships, offshore platform positioning, and port maneuvering, especially under challenging conditions. At Ocean's Marine, we specialise in delivering comprehensive marine solutions, including precise bollard pull assessments and consulting. Our experienced team ensures your vessels are fit for purpose, equipped with the necessary power, and compliant with industry standards. Whether you need support with vessel towing, offshore operations, or detailed engineering assessments, we’ve got you covered! Let us help you maximise the safety, efficiency, and reliability of your marine operations. #MaritimeIndustry #BollardPull #MarineEngineering #NavalArchitecture #TowingOperations #OffshoreSupport #Shipping #MarineSafety #MaritimeExperts #OceanLogistics #PortOperations #TugBoats #Maritime #ShipsAndShipping

SOV / W2W operators, do you know your optimal vessel heading?🚢 It's common to see a significant difference between a weather forecast and actual measurements. 📈 Why rely on a forecast when you can measure it yourself? Check out Chris Moncrieff's insights on how real-time sea condition measurement technology can help you move toward operational excellence: https://hubs.ly/Q02GW1zf0 Why is optimal vessel heading a big deal? 1. Safety of personnel 2. Vessel stability 3. Minimized Impact on Operations / Successful Connection 4. Environmental Protection 5. Cost-Effectiveness / Building trust towards your charterer How can you determine the best vessel heading? Wouldn't it be more reassuring to base your decision on accurately measured environmental conditions rather than only a forecast? #SOV #W2W #Offshore #marine #PSV #AHTS #ocean #gangway #dp #waves

What are the key trends for tugs and towage in 2024? Riviera Maritime Media Ltd takes a look into owners, operators, designers and shipyards are adapting to changing trends in towage requirements coming from the shipping industry’s drive to decarbonize. One key trend emerging is that more tugs are being built to use batteries, electric or hybrid propulsion systems to reduce their environmental impact. E1 Marine is proud to contribute to this evolution through the ongoing development of the M/V Hydrogen One workboat in collaboration with Maritime Partners and Elliot Bay Design Group. When it hits the water, the vessel will be IMO 2030 compliant, meet the USCG’s Subchapter M requirements, and have an operational range of 550 miles before refueling. All of this will be achieved whilst maintaining the highest safety and efficiency standards. Find out more on the top trends: https://lnkd.in/e2wDmkNv #IMO #Safety #Decarbonization
