This document discusses the unique challenges of docking and mooring floating storage and regasification units (FSRUs). It summarizes Trelleborg Marine Systems' comprehensive approach to designing integrated mooring systems for FSRUs. The presentation outlines considerations for mechanical elements, instrumentation, control, monitoring, and emergency release across FSRU, jetty, and liquefied natural gas carrier interfaces. It then discusses the evolution of the project designing the mooring system for the Golar Winter FSRU and Petrobras Bahia regasification terminal in Brazil, including load monitoring, remote release capabilities, and data sharing between vessels and shoreside systems.
Introduction to Floating Storage & Regasification Unit (FSRU)petroEDGE
Over the next 2 or 3 decades it is predicted that gas usage will grow at a much faster rate than oil and become the dominant energy source. Up to some 40% of gas comes from Offshore Fields. The transport of gas in the form of LNG is growing very fast – particularly for longer distance export routes. New offshore opportunities for gas production are being developed with the new technologies of Floating LNG (FLNG).
Inshore or Offshore FSRU’s provide safe, strategic and good location for the receiving terminals for LNG and provide the conversion of the methane from the liquid phase back to the gaseous phase to direct consumer usage.
This 2 day training course covers Gas and LNG activities – their Supply Chain from Onshore and Offshore Gas Fields to Market, with FSRU’s providing the last step by converting the LNG back to usable methane gas for local supply and use. Case Studies and videos will be used to illustrate lessons learned from past successful projects. A DVD of the powerpoint presentation and numerous Industry videos will be distributed with the lecture materials.
This program is a valuable, detailed insight into FSRU
technology and markets. It will benefit:
• National Utility Operators and Power Generation
Providers
• Oil & Gas Engineers
• Naval Architects, Design Engineers, Shipbuilders &
Shipyard Managers
• EPCs
• LNG Terminal & Vessel Operators
• LNG Technology and Equipment Providers

Connecting offshore platforms to a subsea cable system Jerry Brown
This presentation covers some of the key points and lessons learned from the implementation of a 1300km long submarine cable system in the Gulf of Thailand.
• The driver for the project was to improve offshore communications (based on performance, reliability and security) by means of a fiber optic cable network.
• The Oil and Gas Companies chose to select a carrier model rather than take ownership of the subsea system
Do We Really Need TSN in Next-Generation Helicopters? Insights From a Case-StudyRealTime-at-Work (RTaW)
As Ethernet rapidly replaces legacy networks as the core high-speed network in helicopter’s avionics and mission systems, we ask in this paper the question of the technical benefits of migrating to Ethernet Time-Sensitive-Networking (TSN). Indeed, TSN has become a rich toolbox of mechanisms and protocols to address Quality-of-Service (QoS) requirements pertaining to timing and reliability. TSN is quickly becoming the prominent technology for wired high-speed communications in a variety of application domains like automotive, industry 4.0 and telecom. In this context, this work explores the use of TSN timing QoS mechanisms for helicopter’s avionics and mission systems on a case-study representative of the communication requirements of next-generation systems. This study aims to provide quantified insights into what can be expected from TSN in terms of timing, memory usage and extensibility. Paper available at http://hdl.handle.net/10993/48093
China has a rapidly developing submarine cable system manufacturing industry which operates in a healthy competitive manner. Subsea cables can fall into several different system product streams including relatively standard products for long haul telecoms projects (the subject of this paper) and customised products for the Oil & Gas, Scientific Observation Systems, Defence applications and HV subsea cables. While much of the Telecoms product has been sold in the domestic market, Hengtong Marine has broken into the International Market by addressing client concerns over quality and now has a track record for deployed overseas systems. This has been achieved in part by completing an offshore cable system sea trial, which is a requirement of the cable system qualification to ITU-T G-976 & ITU-T G.972 standards. The requirement for a sea trial is a barrier which every cable system producer has to address to achieve international sales. Hengtong Marine is moving forward to promote and improve the image of “Global Quality from China”.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Observations
This presentation is focused on onshore/near shore docking and
mooring FSRU applications
Majority of current projects are floating onshore regas
We are finding that floating regas are more complex from a
mooring system integration standpoint
The docking and mooring system elements tend to be
considered in isolation
LNGC/FSRU – Shipbuilder focusing on primarily FSRU
Ship-to-Ship mooring system hardware
